MACHINE Fon PRESSING AND FINISHING TEXTIL FABRICS.

P SPECIFICATION forming part of Letters Patent No. 257,508, dated May Application tiled February 221, i881. (No model.) Y i by which it may To all 'whom tt may concern Be it known that I, GEORGE W. MILLER, of Woonsocket,Providencecounty,RhodeIsland, have invented certain Improvements in Rotary Cloth-Presses, of which the following is the specification.

My invention relates to machines for press in g and finishing textile fabrics; and itconsists in constructing the same, as fully described hereinafter, so as to subject the fabric to both cold and hot pressure, maintain the pressure i of the cold and hot appliances uniform, facilirolls, brush-shafts,and adjusting devices.

\ rods d, each of which is ,4o

`multa-neously and tate the adjustment and improve the construction of the apparatus.

In the drawings, Figure 1 is a longitudinal sectional' elevation of my improved apparatus;

Fig. 2 an'end view, and Fig. 3 a side elevation,

of the same.

The frame of the niaehineeonsists of the side iieces, A A', suitably constructed to support t e various parts hereinafter described, consistin g mainly of two hollow rolls or cylinders, B B',two hollow beds, CC',and suitable guildehe roll B rotates in fixed bearin gs above the bed C, which moves vertically between guides rt and rests upon leversD, theloose ends of which are connected by rods b to levers E, each'of which has its fulcrum upon the sliding box sup orting the lbearings of the roller B', the bed C beneath the roller B heilig fixed. Giving to this .,construction, 'any downward pressure applied `to the outer end of the lever E will force the' roller B down uponits bed, and si- 4 y with an equal pressure will force-the bed C upward against its roller B. This downwardpressure is exerted and regulated by weights W upon levers F, connected to attached to the outer end of one of the levers E. `The attachment ofthe rods d and levers E is preferably bythe use of some device whereby the pressure upon the leversE ymay beinstantly released in order t0 prevent the goods being burned should the rolls-or beds be too hot.

V ariousdevices-as toggles, cams, Sac-ina y be employed; butI prefer to use eccentrics (if, secnredto a shaft, H,'passin g through slots X at the upper enlarged ends ot' the rods d and arranged between rollers e at the side of each rod. The shaft is provided with a handle, It,

betnrned so as to carry itupward in the slot, and thereby at once relieve the pressure and permit the cloth to travel hetweenI the roll and hed. together in any suitable manner so as to turn in the same direction. ln the drawings, a pinion, 5, on the driving-shaft gears with a cogwheel, 3,011 a shaft,Y, above, which shaft also earriesa pinion, 6, which imparts motion to the roll B by meshing with the cogwheel 2 on the shaft of said roll. f

Motion is imparted t0 the roll B by means of a second pinion, 4, on the end of the shaft Y opposite to that occupied by the pinion 6, which pinion 4 drives the cogvwheel 1 on the end of the shaft of the roll B. Either or both rolls may be,v heated or chilled by means of fluid admitted to and carried from the same, as may also the hollow beds C C', as next described.

Thehollow roll B and bed C are cooled by means of pipes l 0; also, the hollow roll B and bed C are heated by means of hot water orother heating agent circulating from any suitable source through the pipes Il O. These pipes are adjustahly attached to the rollers or beds,

.as shown in Figs. 1 and 2' of the drawings.

In the ironing of fabrics it is sometimes very desirable to subject the fabric first to planishing and pressure between heated surfaces and then to a polishing action between relatively cold surfaces. In such cases it is very important that the heating and planishing devices shall be separate and independent of each other, so that there can heno convection of heat, yet they must beso close together that the fabric can be subjected to the cold polishing while it yet, retains the heat imparted by the planishing-rollers. This I effect by they arrangement shown, where the roll B and hedl C are heated, while the roll B and bedC are not heated, the two being arranged so far apart that heat willnot be transmitted from one totogether that the The rolls are geared Difficulty has heen experienced in this class of machines from the unequal expansion ofthe hollow bed andthe curved facing-plate fi, which is usually made, of a. different metal, which therefore `bucklesduring the opera-tion, preseats an imperfectsnrtaoe, impairing the snrface ofthe fabric, This is especially objectionn able. in finishing paperand other fragile goods which are apt to be torn. I overcome this defeet bylnaking the faeinglllock i of east metal and so securing it to the hed that it can pand freely thereon. As shown, the facingblooli has dovetailed grooves adapted to similar ribs npon the surface of the lied. I do not; here claim this feature, as it will form the 'sahject ofa separate application .for Letters lfat- The fabiic'of paper or textile maY he passed over a stretehingroll, i, 2oiist1lietedasshown, which distends it and takes ont the folds.v ,lt may then pass lirsh beneath the roll.
